ROBERT MCOULLY, OF PHILADELPHIA, PENNSYLVANIA.

CRUSHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 500,598, dated July 4,1893.

Application filed April 25, 1892.

To all whom it may concern.-

Be it known that I, ROBERT MoGULLY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inCrushing- Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

.My invention has relation to gyratory crushing machines of the formhaving a lower cylindrical section having a bottom plate in which islocated the working eccentric and gear Wheel for the gyratory shaft; andit has for its object a construction of such cylindrical section and ofthe bottom plate that the latter is removable from the cylindricalsection whenever desired for repairs or replacement of parts of theactuating mechanism for the shaft, thereby avoiding the dismantling ofthe entire machine for such purposes as has heretofore been customary.

My invention accordingly consists in the combination, construction, andarrangement of the parts as hereinafter more particularly described inthe specifications and pointed out in the claims.

Reference is had to the accompanying drawings, wherein Figure 1, is asectional elevation of the lower cylindrical section for a gyratorycrushing machine embodying my improvements; and Fig. 2 is an elevationof the same, showing door or opening therein for access to the interiorof the cylindrical section.

A represents the cylindrical sections of a gyratory crushing machine,which may be integral with the entire machine or separate therefrom andbolted to the usual other sections as desired. It is provided with theusual outlet chutes a as desired and a bottom plate B with bearing 1)for the eccentric G carrying driving wheel D for gyrating the shaft E inthe usual or desired way. The bottom plate B instead of being integralwith the cylindrical section, A, is made separate therefrom and boltedto it so as to be removable at any time for repairs to the actuatingmechanism for the shaft E without necessitating Serial No. 430,627. (Nomodel.)

dismantlingthe entire crusher. Any suitable manner of securing thebottom plate B to the section A may be used. In the drawings I haveshown the lower inner side of the section A above its bottom providedwith an annular flange a to which the bottom plate B is bolted asindicated at b. As the bottom plate B is located within the supportingor foundation timbers a; for the cylinder A or the machine, byunscrewing the bolts 19 the bottom plate B can be lowered and removedand free access had to the actuating mechanism for the shaft in plate Band cylindrical section A without in any wise dismantling any other partof the machine or mill, which effects a great saving in time and economyin cost of repairs or replacement of said actuating parts. In thecylindrical section A is a counter-shaft opening G and in additionthereto is a man-hole 1-1 with or without door or cover it for oilingtherethrough or for inspection purposes.

K represents a loose cap located upon the top or hub c of the eccentricO. and driving wheel D which cap may be of any suitable construction oras shown in the drawings. This cap has secured to it a chain or' otherloose connection L, the other end of which is connected to a hook or pinZ on the shaft E as shown so as to'follow the latter in its movementswithout using a spline or feather connection between said cap and shaft;such chain or equivalent connection being more effective and economicaland notliable to get out of order, or wear unduly and it prevents thecap or collar from revolving with the gear and eccentric as is the casein crushes of the type indicated as heretofore constructed.

What I claim is 1. A gyratory crushing machine having the actuatingdevices for the shaft located or supported upon the bottom plate and thelatter removable from the machine without dismantling the same,substantially as set forth.

2. A gyratory crushing machine having a lower section A with inwardlyprojecting bottom flange, and removable bottom B secured to said flange,substantially as set forth.

3. In a gyratory crushing machine the lower section or frame A havingchute, countershaft and man-hole side openings, an inwardly projectingbottom flange, and a removable bottom 13 secured to said flange,substantially as set forth.

4. A lower section for a gyratory machine having an open bottom and aninwardly pro- 5 jecting flange, a removable bottom plate bolted to saidflange substantially as set forth.

5. In combination with a gyratory crusher shaft, working eccentric anddriving wheel, a
